INTRODUCTION

Thank you for purchasing the CITIZEN CL-E720/CL-E730 printer. This printer is compatible with the maximum media width (118 mm or 4.65 inch), which has been developed for a wide range of applications such as labels, tags and tickets.

Main Features

This printer can be used for high-speed, high-quality printing thanks to its ARM® Cortex-A9 processor and Citizen's history control IC.

*ARM and Cortex are registered trademarks or trademarks of ARM Limited.

As an energy-efficient product, this printer is compliant with the International Energy Star Program (ENERGY STAR®).

Designed to provide the optimal ribbon tension from the beginning to the end of the ribbon roll, the ARCP ^™ technology insures stable printing position & printed output accuracy by preventing ribbon slippage and ribbon wrinkle.

Label creation and printing is easily accomplished through the use of printer control language emulations. This printer can process either ZPL ^TM or DPL ^TM as standard.

• The printer status can be seen easily and its configuration & setup adjusted easily using the graphic LCD panel.
• The high-lift printhead and mechanism means that media and ribbon can be loaded with ease and it is constructed for easy thermal printhead cleaning, etc.
• Media width adjustment, media thickness adjustment, media sensor adjustment, and ribbon tension adjustment can all be accomplished easily by the user using the colour-coded operator controls.

Ethernet (LAN) and USB 2.0 are standard equipment, for quick data transfer and printing.

Optional RS232C Serial, IEEE1284 Parallel and Wireless LAN (WiFi) are all quickly installed.

The auto-cutter and peeler units are designed so that they can be installed easily.

The adjustable media sensors - which allow the sensors to be positioned in different locations across the media - are standard features making the printer ideal for use with special media.

The interface, power switch etc. are installed towards the back and the top cover opens and closes vertically so that the sides of the printer are not restricted.

Global Configuration Sets

The printer can store three sets of configuration settings that can be recalled quickly and easily. Each "Config Set" (1, 2 or 3) can contain completely different configuration settings for all menu parameters. For example, "Config Set 1" could be configured for 6 ips print speed, print darkness 10. "Config Set 2" next could be 5 ips continuous card media with black mark, print darkness 12. The ability of having three sets of settings is ideal for someone who prints on different media types regularly, for example in a label printing bureau. Global config settings can be printed using the "Test Mode, Print Pattern, Global Config" menu option. It will also display the currently active "Config Set": Global Menu Settings

Media Thickness Adjustment

It may be necessary to adjust the printer according to the thickness of the media being used. This can be done easily by rotating the media adjustment dial to improve the print quality. - Poor print quality across the complete printout means wrongly set media thickness. See this section. - Poor print quality on one side of a printout means wrongly set media width. See next section. Refer to the following table; adjust while performing test printing by turning the dial from the smallest number on the dial to the largest number on the dial one step at a time. 

Media thickness adjustment dial

Media Thickness Dial Position	Suggested media type
0	Direct thermal media (thin media)
1-2	Standard Label media, Direct thermal media
3-5	Thicker media such as synthetic paper, premium grade paper and art paper
6-9	Thick media such as thermal paper (cardboard), cards and tags

These values are guidelines. The exact media being used must be matched with the correct media thickness adjustment position. - When shipped from the factory, it is set at dial 1 or 2. (The factory default setting is indicated on the adjustment gauge label.) - The offset adjustment varies according to the thickness and the hardness of the media. - Dial adjustment may be required depending on the thickness of print and occurrence of ribbon wrinkles. Installing the Media (p.26) Self Print Mode (p.34)

Media Width Adjustment

The head pressure varies according to the width of the media being printed. The head pressure balance must be adjusted according to media width so that constant head pressure is applied to the head. With this printer, it can be adjusted easily by turning the media width adjustment dial. If the printing is blurred or lightly printed on one side or the media moves in a zigzag pattern adjust the head pressure balance. After making an adjustment, confirm the output quality with a test print. 

Caution

When using narrow media, be sure to MAKE this adjustment. (If you do not, the head may be damaged by jamming, etc.) 

Media width adjustment dial

Dial position	Media width mm (inches)	Head pressure
0	19.5 to 23.0 mm (0.77 to 0.90)

The following values are criteria. \- Dial adjustment may be required depending on the thickness of print and occurrence of ribbon wrinkles. Setting the Ribbon (p.30)

Adjusting the Ribbon

If the width of the ribbon changes, a constant pressure will be applied on the guide roller etc. Therefore, it is required to adjust the tension or balance according to the ribbon width. If the ribbon wrinkles or slips, adjust the tension and balance.

Ribbon Tension Adjustment

The adjustment of the ribbon tension can be done in 5 steps in the feeding side (rear side), 3 steps in the winding side (front side), and in 15 different ways. 1. Adjustment in the winding side (front side)

Cleaning

Wipe off any foreign matter such as media dust, dirt and adhesive substances built up around the printhead with the head cleaning pen (head cleaner) provided, and use a soft cloth soaked in ethyl alcohol for the platen etc. It is particularly important to clean the thermal printhead after printing on thermal media for long periods, which will guarantee the print quality and extend the life of the thermal printhead. Note: Always use the head cleaner when cleaning the thermal printhead. 

Thermal printhead Head cleaner


Ribbon guide roller Guide shaft Platen


Caution

Do not use any solvent other than ethyl alcohol. Solvents such as benzene, acetone and thinner will dissolve plastic parts and destroy the thermal printhead, platen and much of the printer! Try to avoid using "excessive amounts" of ethyl alcohol to clean the platen. Excessive use will harden the platen surface prematurely.

XON/XOFF Protocol

Requirements to output X-ON code

● Communication is possible when the power is on. - When the receive buffer has less than 128 byte available, XOFF code is output, then the receive buffer has at least 1024 bytes available.

Requirements to output the X-OFF code

\- When the receive buffer has less than 128 bytes available 

Receive buffer 16kB XOFF 128byte 1024 byte XON

DTR Protocol

Conditions when the DTR signal is "Ready (High)"

All the following conditions are satisfied. ● The receive buffer is 128 byte or more available capacity. \* When the receive buffer has less than 128 bytes available and the DTR signal has changed to BUSY (Low) status, BUSY status is maintained until the capacity of the receive buffer has reached 1024 bytes or more.

Conditions when DTR signal is "Busy (Low)"

\- When the receive buffer has fallen to less than 128 byte available.

Interfaces

Parallel Interface (Option)

Specifications

Transmission mode	8-bit parallel data
Receive buffer size	16kB
Transmission modes	Compatible mode:It is an asynchronous forward direction of the byte width (from host to printer) channel, and the interface line of the data is operated in accordance with signal line definitions of Centronics.NIBBLE mode:Nibble mode is asynchronous reverse channel communication with data transmission controlled by the host computer. In reverse channel transmission, the data is nibble transmitted in two parts using four status lines (Fault, Select, PE, and Busy). And nibble mode can be used along with compatible mode to send data in two directions.ECP mode:ECP mode permits bi-directional asynchronous data transmission, and thanks to its interlock handshake, it does not require the timing necessary with compatible mode.
